BALL-BEARING.

Specification of Letters Patent.

Patented Apr. 19, 1921.

To all to 7mm it may concern:

Be it known that I, Ron-mi) il SnLLnw, a citizen of the United States ofAmerica, residing at New Britain, Connecticut, have invented a new anduseful Ball-Bearing, of which the following is a specification. a

My invention relates to ball bearings and is of particular utility whenemployed in a double row bearing since it facilitates the assembling ofthe bearing in a simple expeditious and accurate fashion.

lln the drawings which show merely a preferred form of the inventionFigure 1 is an edge elevation of a bearing partially in section andpartly broken away. Fig. 2 is a side elevation thereoi partly brokenaway and partly in section.

Fig. 3 is a detail view partly in section.

The bearing includes two bearing rings. One of the rings preferably theouter is made in sections. 1 represents an inner bearing ring. 2-3represent two sections making up the outer bearing ring. 4-5 representthe balls of two separate rows or series. The two bearing rings areprovided with complementary race-ways in whici he balls l-5 are located.One or both of the adjacent edges of the two ring sections 2 -3 havespacer or abutment shoulders 66. These abutments 66 are preferablyarranged at such intervals around the bearing as to support the ringsections at at least three points.

To assemble the bearing the two ring sections 2-3 are separatedsuliiciently to permit the balls l5 to be introduced as shown in 1 and2. The two ring sections QF S are then brought together until theabutments G ll meet. Suitable electric welt apparatus is then broughtinto service to cause the abutments to fuse and become welded so as tounite the two outer ring sections 23 as indie ted at 9.

If desired, destructible shims may be )laced between the balls and therace-wa s l as indicated in my copending application, Serial No.383,524, filer May 22nd, 1920, so that the crowding together of the tworing sections 2-3 will not cause undue binding on the-balls. Une ofthese shims is indicated at 7, Fig. 3. After the ring has cooled, theshim 7 may be cut out or removed in any well known manner, for example,if the shim is of paper it may be rering sections 2 will not actuallycontact (see F 1) but the union of the ring sections 2-3 will becomecomplete and perfect before said intervening edges meet. By localizingthe heat which is to effect the welding it is obvious that deformationor warping of the ring sections is avoided.

l hat I claim is:

1. In a ball bearing, two bearing rings having complementary race-waystherein, one of said rings being formed of two sections, integral spacerabutments between the edges of said ring sections, said spacer abutmentsbeing homogeneously united as by wel di 11 g.

2. In a ball bearing, two bearing rings having complementary raceovaystherein, one of said rings being formed in sections, integral spacerabutinents on one of said sections. said spacer abutinents being weldedto the other section to term a bearing ring.

3. in a ball bearing, two bearing rings having complcmentary race-waystherein, one oi said rings being form d Oit two sections. spacerabutments on said sections, the spacer almtments on opposing sectionsbeing welded together.

4;. b. a ball bearing, two bearing rings having complementary racewaystherein, one said rings being formed of two sections, spacer abutmentson said sections, the spacer abutments on opposing sections being voidedtogether, said sections being free from each other except at ti e weldedpoints.

In a ball bearing, an inner bearing ring having a vice-way th rein, anouter bearing ring having a complementary race-way therein, said outerring being formed in sections, spacer abutments on said sections, theabutments on said sections being welded together to term the completeouter bearing ring.
